Answer:
100 degrees
Step-by-step explanation:
Since triangle ABC is similar to triangle DEF, their angles are basically the same.
All angles of a triangle have to add up to 180.
We are already given two angles: 30 and 50
Add them together: 30 + 50 = 80
Now we subtract the number from 180
180 - 80 = 100
The remaining angle has to be 100 degrees

Isosceles triangle: It has two angles that have the same measure, i.e. the angle opposite the side of the same length
ΔXYA
∠Y=180° - (65+65) = 50°
ΔAYZ
∠Y=(180°-62°):2 = 59°
so ∠XYZ = 50°+59°=109°

Answer:
y-intercept = (0, 8)
x-intercepts = (4, 0) and (-2, 0)
vertex = (1, 9)
5th point = (2, 8)
Step-by-step explanation:
As the coefficient of x² is negative, the curve will be "n" shaped.
y-intercept
crosses the y-axis when x = 0
substitute x = 0 into the function and solve for y:
[tex]\implies y=-(0)^2+(2 \times 0)+8=8[/tex]
Therefore, y-intercept = (0, 8)
x-intercept
crosses the x-axis when y = 0
set the function to zero and solve for x:
[tex]\implies -x^2+2x+8=0[/tex]
[tex]\implies x^2-2x-8=0[/tex]
[tex]\implies (x-4)(x+2)=0[/tex]
[tex]\implies x=4, x=-2[/tex]
Therefore, x-intercepts = (4, 0) and (-2, 0)
vertex
vertex form: [tex]y=a(x-h)^2 +k[/tex], where (h, k) is the vertex
expand vertex equation: [tex]y=ax^2 -2ahx+ah^2 +k[/tex]
compare coefficients with original function: [tex]y=-x^2+2x+8[/tex]
[tex]\implies a=-1, h=1, k=9[/tex]
So vertex = (1, 9)
5th plot point
You can choose any value of x and input it into the equation for y, but for symmetry, I have chosen to find the other value of x (aside x = 0) when y = 8
[tex]\implies -x^2+2x+8=8[/tex]
[tex]\implies -x^2+2x=0[/tex]
[tex]\implies x^2-2x=0[/tex]
[tex]\implies x(x-2)=0[/tex]
[tex]\implies x=0, x=2[/tex]
5th point = (2, 8)

Randy was paid $50 for his first night in the restaurant where he works as a cashier. he worked the rest of the week for $6.50 per hour. the equation, y = 6.50x + 50, represents the amount he made that week. What are the ordered pairs for the equation when you use these x-values: 10 and 20
Step-by-step explanation:
so, we first put 10 in for x :
y = 6.50×10 + 50 = 65 + 50 = $115
and then we put 20 in for x :
y = 6.50×20 + 50 = 130 + 50 = $180
so, the ordered pairs are
(10, 115) and (20, 180)

A rectangle has length 14 cm and width 4cm what is the area of a square that has the same perimeter as the rectangle?
DUE IN 5 MIN!!!!! I GIVE BRAINLIEST!!!!!!! AND I GIVE POINTS IF U WANT!!!!!
Answer:
Given in the attachmentStep-by-step explanation:
Hope this helps ^^"
Answer:
81 cm²
Step-by-step explanation:
Start by finding the perimeter of a rectangle.
[tex]Perimeter = 2(l+w)[/tex]
Plug in the given values into the equation:
[tex]Perimeter=2(14+4)=2(18)=36\ cm[/tex]
Since the perimeter of a square is:
[tex]Perimeter = 4s[/tex]
We can plug 36 cm in for the perimeter to solve for s
[tex]36\ cm=4s[/tex]
Divide both sides by 4
[tex]s=9\ cm[/tex]
The area of a square is:
[tex]Area=s^2[/tex]
Plug in the 9 cm for s
[tex]Area=9^2=81 \ cm^2[/tex]
can someone please help me?

a = -18 s = -36

a bicycle shop is offering a 15% discount on a bike that has an original price of 275. there is an additional 5% discount off the sale price. what is the final price of the bike, including both discounts?
Step-by-step explanation:
• the original price= 275,
275 → 100 %
i) find the price with the 15 % discount
100% - 15% = 85 %
if, 275 → 100 %
100 % → 275
1% → 275 / 100
85 % → (275/100) * 85
= 233. 75
ii) find the add. 5% of the :
sale price = 233. 75
add. discount = 5%
= 5/ 100 * 233.75
= 11.6875
iii) subract the 5% discount from the sale price.
final price = 233. 75 - 11.6875
= 222. 0625

The initial cost to rent a bike is $5. Each hour the bike is rented costs $1.75. is going to rent a bike and can spend at most $10.25. Write and solve an inequality to find how long she can rent the bike.
Answer:
1.75h + 5 ≤ 10.25
number of hours she can rent is a maximum of 3
Step-by-step explanation:
h = hours bike is rented
1.75h + 5 ≤ 10.25
subtract 5 from each side:
1.75h ≤ 5.25
divide each side by 1.75:
h ≤ 3

PLEASE HELP ME: the ratio of cars to trucks on a highway at any given time is 12 to 8. If there are always more than 105 cars on the highway, what is the minimum number of cars that can be on the highway?
Answer:
70
Step-by-step explanation:
First, set up the ratio of c:t, which is 12:8. Then set up your new ratio of c:t, which is 105:?. The way I find the easiest is to divide 105 by 12, which is 8.75, then multiply that by 8, which is 70. To check if it's right, just divide 12 by 8, and 105 by 70, and if they're the same number, you've got it right.
Ps. I'm guessing you meant to ask the minimum number of trucks, not cars.

Answer:
x = 130°
y = 50°
Step-by-step explanation:
x = 130° (Exterior alternate angles)
x + y = 180° (Angles in linear pair)
y = 180° - x
y = 180°- 130°
y = 50°
The solution to the problem in the figure attached in the question is: x = 130°, y = 50°
What are alternate angles?Alternate angles are angles that are formed in a situation whereby a line intersects two other lines, which lie on opposite sides of a transverse line and on contrasting proximate sides of the other lines.
From the given figure:
Angle x is an alternate angle to angle 130°.
Thus, x = 130°
Using the sum of angles on a straight line:
x + y = 180°
130° + y = 180°
y = 180° - 130°
y = 50°
